Wow Alan,
That's surprising that it's still there. That was already a pretty good deal imo. You could probably walk in and offer them $400 flat and they'd likely take it if it's been sitting that long.
My factory TC 17 HMR carbine barrel is incredibly accurate. I have amazed my prairie dog shooting buddies with it. Even if you didn't want the HMR, the "new" (old) 17 Hornet would be cheap and easy to make from it.
I wouldn't go 17 WSM though, that round will be DOA. The 17 HMR is far too entrenched, ammo and guns are far too plentiful. Low numbers of WSM production rifles is likely, and it will go the way of the dodo bird. In 5 years you'll be struggling to find any ammo for it, and you'll be sitting on it hoping for a resurgence in interest before you die. Aka like the Rem 5mm rimfire. Anyone remember that one? How about the 17 HM2? Both good rounds, but both are dead now.
